Stirring device for circular tube air-suction seeding unit

Abstract

The invention relates to a main part of a seeder in agricultural machinery. Seeding quality depends on the seed charging rate of a seeding unit, and the seed charging rate of the circular tube air-suction seeding unit depends on the size of air volume and the fluidity of seeds. When the air volume is a fixed value, the fluidity of the seeds directly affects the seed charging rate. The invention provides a stirring device for the circular tube air-suction seeding unit, which can increase the fluidity of the seeds, increases the adsorption force of the seeding unit, and enhances the seed charging rate. The centered seed sucking seam on a shaft is provided with a stirring wheel, and the butt-seam installation of the stirring wheel can enhance the fluidity of the seeds in a seed charging area. The device is fixed on a seed box to continuously and smoothly work. One end of the shaft is provided with a gear wheel which is externally engaged with a gear wheel on a seeding unit, so that the stirring wheel is reversely rotated following the seeding unit.

Description

technical field [0001] The present invention relates to a main part of a planter in agricultural machinery Background technique [0002] At present, the commonly used seed metering devices for seeders are divided into two types: mechanical type and pneumatic type. Pneumatic seed metering device is divided into air suction type and air blowing type. Air-suction seed metering devices commonly used in production are mainly used for sowing corn, and most of the seed metering devices for sowing wheat are groove wheel seed metering devices. Seeding requirements; but for the pursuit of high yield and higher requirements for sowing quality, the grooved wheel seed metering device has an adverse effect on the uniformity of sowing due to the pulsation of its seeding. Air-suction corn precision seeders are commonly used with round tube holes, disc holes, and round tube gaps. Air-suction wheat precision seeders are only in the experimental research stage at home and abroad. [0003] T...
